The study of previous or past climate
changes which took place over a large timespan from the early history of
the emergence of the earth is known as Paleoclimatology. For this study
researchers use previous evidences known as proxies to understand about the
past climate. Proxies are environmental proofs like tree rings, diatoms, coral reefs, sediments, ice cores, rocks, glaciers and, ice caps which gives us the details
as to how the transformation in climate took place. They also help us in getting
an idea regarding the past climate and envisaging the future climate. The
importance of Paleoclimatology is that it gives a picture of how climate has
been changing from the past and how the formation of present climate took place.
The data from the paleoclimate study gives information regarding how plant and
animal kingdom responded and adapted to the changes in the climate. The study
also tells us that the process of climate
change is a continuous phenomenon. Climate
Change 2019 will give us an insight into the past, present and
future climate of the world.
